It just looks that way that backlight is blueish, it's closer to cold white in real life. And I can dime it with the whole instrument cluster so it won't distract me while driving trought the night
The LCD will be tehre permanently, but now I'm planning to add few new features to my instrument cluster and replace Arduino board with a simple board with Atmega328. But I don't think I'll mess with the colour of the LCD display. I haven't driven Berta wit this mod yet so I may change my mind soon
